8.2.2 Mounting process and soldering recommendations
Reflow profiles are to be selected according to u-blox recommendations. See JODY-W2 series System
integration manual [2] for more information.
8.2.3 ESD handling precautions
⚠ JODY-W2 series modules are Electrostatic Sensitive Devices (ESD). Observe precautions for
handling! Failure to observe these precautions can result in severe damage to the Wi-Fi receiver!
Wi-Fi transceivers are Electrostatic Sensitive Devices (ESD) and require special precautions during
handling. To minimize the risk of damage caused by electrostatic charges, be sure to handle the
patch antennas with care. In addition to standard ESD safety practices, the following measures
should be observed when handling the receiver:
 Unless there is a galvanic coupling between
the local GND (on the work bench, or similar)
and the PCB GND, the first point of contact
when handling the PCB must always be
between the local GND and PCB GND.
 Be sure to ground the module before
mounting an antenna patch.
 When handling the RF pin, avoid any contact
with charged capacitors. Also be careful
when contacting materials that can develop
charges, like the patch antenna (~10 pF),
coaxial cable (~50-80 pF/m), soldering iron,
and so on.
 To prevent electrostatic discharge through
the RF input, do not touch any exposed
antenna area. If there is any risk that the
exposed antenna area might be touched in a
non-ESD protected work area, be sure to
implement proper ESD protection measures
in the application design.
 When soldering RF connectors and patch
antennas to the RF pin of the receiver, be
sure to use an ESD safe soldering iron (tip).
